How to start with FLTK C

Windows:
Download and extract fltk-c.1.3.3.zip with all folders on any drive:
optional run buildall.bat

Linux:
Download and extract fltk-c.1.3.3.zip with all folders in your home folder:
copy the extracted library to /usr/lib
ubuntu: sudo cp libfltk-c*.so /usr/lib
slackware: su -c "cp libfltk-c*.so /usr/lib"
or any other distro as root: cp libfltk-c*.so /usr/lib
optional run buildall.sh

What is the difference to the "old" FLTK bindings?

What is the difference to the "old" FLTK bindings?

It's new :-)
I changed some internal FLTK C++ stuff.
Fixed some old known bugs.
Using freetype font rendering on Linux.
Rotated text output on Linux are enabled now.
It's prepared for ARM devices now. (no OpenGL, no overlays ...)
Removed hidden strucs from C wrapper.

You are wrong It was never only one include file !
It was and is seperated in logical unit's.

Joshy

fltk-c.bi include this files:

Code: Select all

#include "fltk-main.bi" ' 344 KB
#include "fltk-tools.bi" '15 KB
#ifndef __FB_ARM__
#include "fltk-gl.bi" ' 8 KB
#include "fltk-glut.bi" ' 22 KB
#endif

[fxm]

Yes for my test example, now "fltk-main.bi" instead of old "fltk-c.bi" is sufficient.

Rasbian / debian ARM port available and tested on Raspberry PI model B.

Should work on all Raspberry PI A, B, Zero maybe on PI 2/3 also but I'm not sure.

If you have a Raspberry PI 2 or 3 let me know your test result please.

If you don't have a Raspberry PI I posted a short tutorial how to run a PI via QEMU.
(on a modern / fast PC it can be run with the native speed of a real PI or faster.)

Thank you for this update !

However, it seems that the import library libfltk...dll.a is missing in the Windows archive.

However, it seems that the import library libfltk...dll.a is missing in the Windows archive.

Is included now.

hello D.J.Peters, first I want to thank you for all the work you put into this library :)
I tested on the Pi 3 and everything compiled ok without warnings, but a couple of tests did not show output Screeninfo and FL_WindowFullscreen, have not run every program because there are so many :)

Hello,
I tried to use the FLTK library last night on my home computer which is using FBC version 0.9xxx. The compiler stopped near line 465 saying FLTK-glut.bi used an unknown variable Boolean. Do I need to upgrade my compiler version to handle the new boolean types? Also, I was wanting to use the FLTK widget to select a directory - is that widget included in this Freebasic library?

Looks like a great tool. I'm looking forward to using it.

Thanks,
Darren

Yes. Booleans are 1.0 and above.

[MrSwiss]

Yes. Booleans are 1.0 and above.

Not correct: 1.00.0 = FBC 64 bit! = NEW (and still, the 32 bit).
Booleans are >= 1.04.0 ...
This means: Yes, you MUST update, to use Boolean Variables. (current Version = 1.05.0)
